2015-05-01[media] v4l2: replace s_mbus_fmt by set_fmtHans Verkuil5-19/+60
The s_mbus_fmt video op is a duplicate of the pad op. Replace all uses in sub-devices by the set_fmt() pad op. Signed-off-by: Hans Verkuil <hans.verkuil@cisco.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@osg.samsung.com>
2015-05-01[media] v4l2: replace try_mbus_fmt by set_fmtHans Verkuil20-265/+287
The try_mbus_fmt video op is a duplicate of the pad op. Replace all uses in sub-devices by the set_fmt() pad op. Since try_mbus_fmt and s_mbus_fmt both map to the set_fmt pad op (but with a different 'which' argument), this patch will replace both try_mbus_fmt and s_mbus_fmt by set_fmt.

ov7670_s_exp() checks read error for 2 registers: REG_COM1 and REG_COM8. But, although it uses the value latter, it doesn't check errors on REG_AECHH read.

Thankfully, there's just one place at saa717x driver that uses multibyte read (for status report, via printk). Yet, let's fix it. From saa717x_write(), it is clear that the bytes are in little endian: mm1[4] = (value >> 16) & 0xff; mm1[3] = (value >> 8) & 0xff; mm1[2] = value & 0xff; So, the same order should be valid for read too.

2015-03-23[media] v4l2-subdev: replace v4l2_subdev_fh by v4l2_subdev_pad_configHans Verkuil18-243/+249
If a subdevice pad op is called from a bridge driver, then there is no v4l2_subdev_fh struct that can be passed to the subdevice. This made it hard to use such subdevs from a bridge driver. This patch replaces the v4l2_subdev_fh pointer by a v4l2_subdev_pad_config pointer in the pad ops. This allows bridge drivers to use the various try_ pad ops by creating a v4l2_subdev_pad_config struct and passing it along to the pad op. The v4l2_subdev_get_try_* macros had to be changed because of this, so I also took the opportunity to use the full name of the v4l2_subdev_get_try_* functions in the __V4L2_SUBDEV_MK_GET_TRY macro arguments: if you now do 'git grep v4l2_subdev_get_try_format' you will actually find the header where it is defined. One remark regarding the drivers/staging/media/davinci_vpfe patches: the *_init_formats() functions assumed that fh could be NULL. However, that's not true for this driver, it's always set. This is almost certainly a copy and paste from the omap3isp driver. I've updated the code to reflect the fact that fh is never NULL.

2015-02-26[media] cx25840: better document the media controller TODOMauro Carvalho Chehab1-1/+14
Analog video inputs are the tuner, plus composite, svideo, etc, e. g. the input pat should actually be like: ___________ TUNER --------> | | | | SVIDEO .......> | cx25840 | | | COMPOSITE1 ...> |_________| (in the above, dashes represent the enabled link, and periods represent the disabled ones) In other words, if we want to properly represent the pipeline, it should be possible to see via the media controller if the tuner is being used as an image source, or if the source is something else. I didn't map those other inputs here yet, due to a few things: - The extra inputs would require subdevs that won't be controlled - I was in doubt about the best way for doing that - That would likely require some extra setup for cx25840 caller drivers, in order to represent what of the possible internal inputs are actually used on each specific board Actually, at least for now, I was unable to see much benefit on adding such map now, so let's just document it, as this could be added later on, as needed.

Instead of keeping the media controller entity not initialized, fill it and create the pads for cx25840. Signed-off-by: Mauro Carvalho Chehab <mchehab@osg.samsung.com>
2015-02-02[media] adv7180: Add fast switch supportLars-Peter Clausen1-0/+29
In fast switch mode the adv7180 (and similar) can lock onto a new signal faster when switching between different inputs. As a downside though it is no longer able to auto-detect the incoming format. The fast switch mode is exposed as a boolean v4l control that allows userspace applications to either enable or disable fast switch mode.

2015-02-02[media] adv7180: Add I2P supportLars-Peter Clausen1-8/+148
Some of the devices supported by this driver have a interlaced-to- progressive converter which can optionally be enabled. This patch adds support for enabling and disabling the I2P converter on such devices. I2P mode can be enabled by selecting V4L2_FIELD_NONE instead of V4L2_FIELD_INTERLACED for the format.

2015-02-02[media] adv7180: Add support for the adv7280-m/adv7281-m/adv7281-ma/adv7282-mLars-Peter Clausen1-16/+154
This patch adds support for the adv7280-m/adv2781-m/adv7281-ma/adv7282-m devices to the adv7180 driver. They are very similar to the adv7280/adv7281/adv7282 but instead of parallel video out they feature a MIPI CSI2 transmitter. The CSI2 transmitter is configured via a separate I2C address, so we need to register a dummy device for it.
